Description

Technical Field

[0001] This utility model relates to the field of nutrient agar storage and preparation technology, and more specifically, to an integrated nutrient agar storage and preparation bag. Background Technology

[0002] Nutrient agar, as a basic microbial culture medium, has core components including beef extract, peptone, sodium chloride, and agar. In existing technologies, nutrient agar culture medium products are typically prepared as powder and stored in tanks for sale. Therefore, when preparing the culture medium, it is necessary to open the tank, take out the powder, and then mix it with pure water to form a paste before use. However, since a tank of nutrient agar cannot be used up in a short period, repeated use poses a risk of cross-contamination and spoilage of the powder within the tank. Furthermore, when quantitatively preparing the culture medium, repeated powder taking is required, which is not only inconvenient but also makes it difficult to ensure accurate weighing, further exacerbating cross-contamination and spoilage.

[0003] Based on the above description, there is an urgent need for an integrated nutrient agar storage and dispensing bag that can both store nutrient agar and facilitate quantitative dispensing. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated nutrient agar storage and preparation bag, which aims to solve the technical problems of inconvenience in taking out nutrient agar and the risk of cross-contamination and deterioration of powder in the tank when using existing tank storage.

[0005] The embodiments of this utility model are achieved through the following technical solutions:

[0006] An integrated nutrient agar storage and preparation bag includes a bag body and a material guiding assembly; the bag body has a partition air bladder inside; the bag body is divided into a pure water chamber and a powder chamber by the partition air bladder; the material guiding assembly is connected to the powder chamber; the material guiding assembly passes through the bag body.

[0007] Preferably, a sealing component is provided at one end of the powder chamber near the separating airbag.

[0008] Preferably, the sealing assembly includes a silicone groove and a silicone strip; the silicone groove and the silicone strip are disposed opposite each other inside the bag body; the silicone strip is embedded in the cavity of the silicone groove.

[0009] Preferably, the outer side of the bag body is provided with a first pressure strip and a second pressure strip; the first pressure strip is disposed opposite to the side of the bag body away from the silicone groove; the second pressure strip is disposed opposite to the side of the bag body away from the silicone strip.

[0010] Preferably, both ends of the first pressure strip extend out of the side of the bag body; both ends of the second pressure strip extend out of the side of the bag body and are respectively engaged with the two ends of the first pressure strip.

[0011] Preferably, the bag body has a kneading part at one end near the material guiding assembly; the kneading part is located on one side of the powder cavity.

[0012] Preferably, the bag body has a plurality of protrusions corresponding to the kneading part on the outer side of the end near the separating air bladder.

[0013] Preferably, the material guiding assembly includes an insert and a plug; the insert is inserted through one corner of the bag body; the insert communicates with the powder chamber; the plug is inserted through the interior of the insert and engages with the insert.

[0014] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0015] This invention uses a dividing airbag to separate the bag into two chambers: a pure water chamber and a powder chamber. The pure water chamber stores a fixed amount of pure water, while the powder chamber stores a fixed amount of nutrient agar powder. When needed, the dividing airbag is squeezed to rupture it, allowing pure water to flow into the powder chamber and mix with the nutrient agar powder, thus achieving ingredient mixing.

Detailed Implementation

[0023] The specific implementation method is described below with reference to the accompanying drawings.

[0024] Example 1

[0025] Please see Figures 1 to 6 The present invention provides the following technical solution: an integrated nutrient agar storage and preparation bag, which is suitable for storing and preparing nutrient agar.

[0026] Specifically, such as Figure 1 and Figure 5 As shown, an integrated nutrient agar storage and preparation bag includes a bag body 1 and a material guiding component 2; the bag body 1 is provided with a dividing air bladder 3 inside; the bag body 1 is divided into a pure water chamber 11 and a powder chamber 12 by the dividing air bladder 3; the material guiding component 2 is connected to the powder chamber 12; the material guiding component 2 passes through the bag body 1.

[0027] In this embodiment, the bag 1 is completely divided into two independent chambers by the separating airbag 3, namely the pure water chamber 11 and the powder chamber 12. Before the separating airbag 3 is squeezed, the pure water chamber 11 and the powder chamber 12 are not connected. The pure water chamber 11 is used to store pure water in a quantitative manner, and the powder chamber 12 is used to store nutrient agar powder in a quantitative manner. When needed, the separating airbag 3 is squeezed to rupture it, and then pure water is introduced into the powder chamber 12, so that the pure water and nutrient agar powder are mixed, thereby realizing the preparation. Compared with the traditional method of repeatedly scooping nutrient agar powder from the tank for weighing and then adding water for preparation, this embodiment is convenient for storing nutrient agar and convenient for direct preparation. There is no need for repeated scooping or manual weighing, which is convenient and practical. It also solves the problems of contamination and deterioration of nutrient agar stored in traditional tanks.

[0028] In this embodiment, the separator airbag 3 is actually made by dividing the bag body 1 into a separate cavity using multiple separator membranes and then introducing inert gas. To ensure the rupture location of the separator airbag 3 when it is squeezed, the middle part of the separator membrane near the pure water cavity 11 and the powder cavity 12 is locally cut to make it locally thinner. When squeezed, this local position will rupture first, ensuring that pure water flows into the powder cavity 12 without damaging the bag body 1.

[0029] The specific implementation process is as follows: Hold the dividing airbag 3 part of the bag body 1 and keep the bag body 1 vertical. Press the dividing airbag 3 to open the pure water chamber 11 and the powder chamber 12. Further squeeze the outside of the bag body 1 of the pure water chamber 11 to quickly squeeze the pure water into the powder chamber. Then, by kneading the powder chamber 12 part of the bag body 1, the pure water and nutrient agar powder are fully mixed. After being mixed evenly, the mixed nutrient agar is squeezed out and used directly by squeezing the bag body 1 and the material guiding component 2.

[0030] Specifically, such as Figure 2 and Figure 4 As shown, a sealing assembly 4 is provided at one end of the powder chamber 12 near the separating airbag 3. The sealing assembly 4 includes a silicone groove 41 and a silicone strip 42; the silicone groove 41 and the silicone strip 42 are disposed opposite each other inside the bag body 1; the silicone strip 42 is embedded in the groove cavity of the silicone groove 41.

[0031] In this embodiment, both the silicone groove 41 and the silicone strip 42 are made of elastic silicone material. After pure water is put into the powder chamber, the silicone strip 42 is embedded into the silicone groove 41 by pressing, thereby separating the pure water chamber 11 again, and further separating a mixing chamber 12 on the powder chamber 12 extrusion. During the mixing process, the bag 1 near the mixing chamber is kneaded, thereby avoiding the material from sticking to the separating air bag 3 and the pure water chamber 11 during the mixing process, which would make it inconvenient to extrude and use.

[0032] Specifically, such as Figure 1 and Figure 5 As shown, a first pressure strip 5 and a second pressure strip 6 are provided opposite to each other on the outside of the bag body 1; the first pressure strip 5 is located opposite to the side of the bag body 1 away from the silicone groove 41; the second pressure strip 6 is located opposite to the side of the bag body 1 away from the silicone strip 42. Both ends of the first pressure strip 5 extend out of the side of the bag body 1; both ends of the second pressure strip 6 extend out of the side of the bag body 1 and are respectively engaged with the two ends of the first pressure strip 5.

[0033] In this embodiment, the first pressure strip 5 and the second pressure strip 6 are made of rigid plastic, which not only facilitates the quick and accurate embedding of the silicone strip 42 into the silicone groove 41, but also facilitates the separation function. Furthermore, it facilitates the quick folding of the bag body 1 after separation, further avoiding the situation where materials are squeezed into the pure water cavity during the mixing process, resulting in residues during subsequent use.

[0034] In this embodiment, the first pressure strip 5 and the second pressure strip 6 are respectively set as an existing card slot and an elastic plastic card block, which are squeezed and deformed to be stuck in the card slot.

[0035] Specifically, such as Figure 1 and Figure 4As shown, the bag body 1 has a kneading part 7 at one end near the material guiding assembly 2; the kneading part 7 is located on one side of the powder chamber 12. The bag body 1 has multiple protrusions 8 corresponding to the kneading part 7 at one end near the separating air bladder 3.

[0036] In this embodiment, the kneading part 7 is made of thermoplastic polyurethane film or silicone film, which has both toughness and elasticity; the protrusions 8 are made of silicone or plastic material, which have a certain hardness; based on the first pressure strip 5 and the second pressure strip 6 in the middle of the bag body 1, the bag body 1 is folded over, so that the end with multiple protrusions 8 is turned to the kneading part 7, which makes it easier to manually and indirectly knead and mix the materials evenly, and can also avoid damage to the kneading part 7 caused by fingernails or excessive force.

[0037] Specifically, such as Figure 5 and Figure 6 As shown, the material guiding assembly 2 includes an insert tube 21 and a plug 22; the insert tube 21 is inserted through one corner of the bag body 1; the insert tube 21 is connected to the powder chamber 12; the plug 22 is inserted inside the insert tube 21 and is engaged with the insert tube 21.

[0038] In this embodiment, after the nutrient agar is mixed, the plug 22 is pulled out, and the material is further squeezed out of the tube 21 by compression; wherein, the tube 21 and the bag body 1 are an integral structure and are firmly connected by means of bonding or other methods.
